The Exo Terra Reptile UVB300 is specifically tailored for reptiles that thrive in environments with intense, direct sunlight, such as deserts or open savannahs.
With its 14% UVB output, this bulb delivers the highest UV intensity among the T5 series, meeting the needs of reptiles requiring high levels of UVB exposure. Supporting Ferguson Zones 3-4 and the Euphotic and Heliophotic Zones, it provides the UVB necessary for open and mid-day sun baskers. The UVB300 is critical for maximizing vitamin D3 synthesis, which is essential for robust bone growth, healthy shells, and preventing metabolic bone disease (MBD). This bulb is ideal for large enclosures or terrariums with minimal shading, replicating the intense sunlight found in arid and semi-arid regions. Its high UV output ensures reptiles receive adequate exposure even at greater distances from the bulb. To avoid overexposure, the positioning and distance from the basking area should be carefully considered. When used alongside basking lights and proper thermal setups, the UVB300 creates a complete and enriching environment that supports the health and natural behaviors of reptiles in high-UV habitats.
Exo Terra®’s exceptional T5 lamps are crafted in Germany to the highest quality standard, ensuring a prolonged UV output of 12+ months for lasting performance. With its intense output of UVA and UVB rays – combined with a well-balanced visible light spectrum – the Exo Terra® Reptile UVB300 T5 Very High Output Bulb is specifically designed to meet the needs of reptiles basking in open or midday sun in the Euphotic or Heliophotic Zones. The intensity of the emissions varies depending on the distance from the basking area.
Higher levels of UV are vital for the physiological wellbeing of these animals, which thrive under intense sunlight. They actively interact with their environment when the sun is high or even at its peak – showcasing an exemplary adaptation to solar intensity by optimising body temperature and UVB intake during basking behaviour.
The Exo Terra® Reptile UVB300 VHO T5 Bulb helps promote healthy Vitamin D3 synthesis, which in turn facilitates improved calcium absorption – safeguarding against Metabolic Bone Disease. Its UVA and UVB emissions surpass those of traditional T8 bulbs and energy-efficient alternatives, while enhanced UVB penetration extends its suitability for use in taller terrariums or those equipped with denser screens.
For optimal results and prolonged lifespan of the bulb, we recommend using it in conjunction with the Exo Terra® T5 Terrarium Top High-Performance Reptile UVB Fixture.
Long-lasting UVB output (12+ months).
The longer sizes can be placed across multiple terrariums.
Keepers can use the UV Index reference values to ensure that animals are exposed to an appropriate level of UV when basking. Creating a gradient – from highest safe UV index at the basking area to lowest UV index in cooler areas – means they can completely self-regulate alongside their thermoregulatory behaviours. They should not be allowed to expose themselves to more than a safe maximum and should have the freedom to escape all light completely with areas of zero UV and Infrared. This can be achieved by strategically adding plants, hides, and decorative items to create shaded zones.
To support the efficient conversion of vitamin D3 and enhance various metabolic and hormonal processes, it is beneficial to ensure that UV light exposure is complemented by an ample supply of infrared-A (NIR) radiation. The most effective sources can be found in Tungsten Halogen or standard Incandescent spot bulbs, such as the Exo Terra Intense Basking Spot or Halogen Basking Spot. This combination promotes optimal body temperature regulation and overall well-being.
